ZA Free Periodically blocks internet activity using bitTorrent

Hi,
i use 9.1 free edition at a Win7 PC. Trying to download files with bitTorrent i see that, at random times, internet activity stops for 1-2 minutes and the program seems to not responding (cursor hourglass) and then starts again. The same time all my programs that require internet access have the same problem. During this problem zlclient has 10-20% activity and when falls to 0% the problem ends.
What is happenig, please ?

May be when your system is writing data to the hard disk? I have seen this on some 'old' over charged system. Remove ZA 9.1 and then install ZA 9.2.042.000, keep the default settings and see if there is any improvement.
